6 Claims.

This invention relates to wall coping such as commonly is used upon the upper course of a masonry structure, and more especially it relates to wall coping that consists of clay or tile sections positionable in end-to-end relation and having end formations that intert with adjacent sections.

The invention is an improvement upon my prior U. S. Patent No. 1,972,819, issued September 4, 1934. The coping constituting the subject matter of the aforesaid patent consisted of tile sections, each of which sections comprised a longitudinally extending tongue projecting from one end thereof adapted to be inserted beneath the top wall of an adjacent section, and formed on its under side with two parallel, depending, undercut ribs adapted to rest upon the top of a wall and mechanically to interlock with a mortar course upon said wall. The arrangement was satisfactory in cases where the coping was low, that is, positioned close to the top of a wall, but when a taller coping was desired, the provision of taller undercut ribs on the coping sections presented manufacturing difficulties, such as the prevention of breakage of the ribs during the forming and firing of the tiles. It is to the relief of this condition that this invention is directed.

The chief object of the present invention, therefore, is to provide an improved sectional wall coping of the character mentioned. More specifically, the invention aims to provide coping units of'l greater height than shown in the aforementioned patent and which interlock with the mortar course on top of a wall, yet which do not require longitudinal supporting ribs of increased height for achieving this purpose. Another object is to provide an improved wall coping of the character mentioned wherein the supporting elements of the coping are subject to less breakage during manufacture. Other objects will be manifest as the specification proceeds.

Of the accompanying drawing:

Figure 1 is a plan view of a wall coping embodying the invention, a part thereof being broken away and in section;

Figure 2 is a side elevation thereof, a part being broken away and in section;

Figure 3 is a fragmentary perspective View of one end portion of a coping section;

Figure 4 is an end elevation of the opposite end of the coping section shown in Fig. 3;

Figure 5 is a section on the line 5--5 of Fig. 2; and

Figure 6 is a section on the line 6-6 of Fig. 2.

Referring to the drawing, there is shown a wall coping comprising a succession of units or sections IU, I0 that are mounted atop of a well II, the latter being shown, for illustrative purposes, as a brick wall. Each section Ill is composed of tile or baked clay of suitable or desired thickness for economical and effective firing, and preferably is of concavo-convex form in transverse section. Opposite lateral margins of the section are provided with integral depending skirts or side walls I2, I2 adapted to overlap the joint between the coping and the wall upon which it is mounted.

For interlocking each coping section I 0 with the mortar course on the top of wall I I, the confronting faces of the skirt portions I2 are formed with respective laterally inwardly projecting, longitudinally extending ribs I4, which ribs have a flat bottom face disposed somewhat above the lower, free margins of the skirts I2. At the bottom of each rib I4 there is a longitudinally extending undercut recess I5 disposed between the rib and adjacent skirt, the arrangement being such that mortar I6 between the coping section and the Wall II will flow into said recesses I5, as shown in Figures 5 and 6, and thus interlock the section with said mortar course. At one end of the coping section the ribs I4 terminate inwardly of the end thereof, as shown in Figs. 1 and 2, and at the Opposite end of the section they project beyond the end thereof and are integral with a tongue structure presently to be described. Preferably the skirts I2 are somewhat thinner below the ribs I4 than above them, as is cleafflv shown in Figures 3 to 6 of the drawing. I

Each section I0 has at one end thereof a portion I8 extending inwardly or downwardly of the concave or under side thereof, and inwardly and laterally of the skirt portions I2 thereof, said portion I8 being formed with a projecting tongue I9 that extends beyond the end of the coping. Said tongue is arcuate in its medial region and concentric with the arcuate top of the coping, the ends of said arcuate medial region connecting with vertically disposed portions Ilia, |911 that are substantially parallel to the skirt portions I'2. At their lower ends the respective vertical portions I 9a of the tongue merge with the projecting end portions of the ribs I4, as is best shown in Fig. 3. The convex face of the medial portion of the tongue I9 is disposed somewhat inwardly of the concave bottom face of the medial portion of the coping section, and the distance between the outer lateral faces of the vertical tongue portions 19a is less than the distance between the inner faces of the skirts I2. The arrangement is such that the tongue i9 is able to extend beneath the complementally shaped top of the confronting end portion of an adjacent coping section, and between the skirt portions I2 thereof, the end portion of the adjacent section thus constituting a socket for said tongue and the skirts of adjoining sections being in end-to-end abutment.

Theimproved coping sections are readily and electively joined to provide an improved joint that prevents moisture from nding its way therethrough and into the wall structure Il. Cement or mortar is applied on top of the tongue I9 of a previously positioned coping section 4andV to the outer faces of vertical portions |9a of the tongue. Then upon application of asuc'.- ceeding coping section to the Wall, the mortar is squeezed between the coping members and into the joint between the confronting. end faces of the sections including the skirts I2 thereof..

Modification may be resorted to without'departing Yfrom the spiritzof the invention or the scope .thereof asfdenedby the appended claims.

Vvh'atis 'claimed is:

l. A: coping unit comprising a body'portion that is substantially longitudinally flat and having ,longitudinally extending .skirtrportions coextensive with its lateral marginsand depending therefrom, and laterally projecting 'supporting ribs formed'on the confronting faces of said skirtportionsintermediate.'the upper and lower limits thereof', each rib having a downwardly extending endportion which is spacedV from the skirtion which it Vis formed.

2; A coping unit comprising a body portion that. is substantially'longitudinally fiat and hav- 2 ing, .longitudinally extending skirt: portions: coextensive with itslateral. 'marginsiand depending therefrom, andi laterally projecting vsupporting ribs formed on the"confrontingifaces of 'said skirt portions intermediate the `upper kand vlower limits thereof with the. bottom face of each rib` disposed above the bottom. margin of the adjacent skirt portion, each ribV being so shaped as to dene an undercut recess between the lower portion thereof and the adjacent skirt.

3. A coping unit comprising a body portion f that is substantially longitudinally fiat and having longitudinally extending skirt portions coextensve with its lateral margins and depending therefrom, and laterally projecting supporting ribs formed on the. confronting faces of said skirt portions intermediate the upper and lower limits of the latter, said ribs terminating short of one end of said skirts and projecting beyond the opposite end of said skirts.

4. A coping unit comprising a body portion that is substantially longitudinally nat and having; longitudinally extending skirt portions coof said structure extending inwardlyA from` said Y body portion and skirts, a 4tongue on the inner end of said wall projecting. beyondxthe adjacent end of the structure, said tongue being'disposed below said body portionY and inwardlyl of the skirts thereon, and laterally projectinggsupporting ribs formed on the confronting faces of thev skirt portions and. extending.. longitudi- `nally thereof, said ribsmerging with the' tonguesupporting wall at one-endof the unit.Y

6. A combination as defined in claim 5 including an undercutrecess formed between each rib and skirton which it is formed;
